First previewed back in March, today we get a better look at the all-new Nike Air Tech Challenge IV Low retro. In an arguably quite underwhelming presentation compared to the colorful original releases of the Tech Challenge IV, the retro tennis silhouette made famous by Andre Agassi goes for a neutral Anthracite tone for its fully synthetic upper. For added details, the heel features a faux carbon fiber material while the midsole gets some grey speckling. Even devoid of all the OG Tech Challenge IV’s flair, are these a solid summer pick up? Let us know your thoughts in the comments below, and you can find them now at select NSW retailers like Heist.
